GEORGE L. REYNOLDS, OF NEWARK, NEW JERSEY.

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 428,413, dated May 20,1890.

Application filed August 28, 1889 Serial No. 322,189. (No model.)

To all whom. it may concern.-

Be it known that I, GEORGE L. REvNoLDs, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in WVindow- Screens; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and. to letters of reference markedthereon, which form a part of this specification.

The object of this invention is to providea cheap and effectivemosquito-screen frame capable of being quickly and readily adjusted towindows of varying widths, and free from certain objections inherent inframes of a similar character heretofore prodnced; and the inventionconsists in the improved frame and in the arrangements and combinationsof the several parts thereof, as hereinafter set forth, and finallypointed out in the claim.

Referring to the accompanying drawings, Figure 1 represents a frontelevation of a window and of my improved mosquito-screen frame adjustedtherein. Fig. 2 represents an enlarged elevation of a detached portionof said frame, showing certain special features of construction. Fig. 3is a similar view showing in section a modification of said features;and Figs. 4, 5, 6, 7, and 8 are detail views.

Similar letters of reference indicate like parts in each figure wherethey occur.

In carrying out my invention I construct the main body of the frame A Bin the usual manner, except the stiles A A, which are provided withtongues 0, which enter and work in grooves 0 formed in supplementarystiles D, as will be understood upon reference more particularly toFigs. 2, 3, and 5. These stiles are arranged so as to be adjustablelaterally to the extent of the depth of the said tongues and grooves, asthe said figures will show, and to such extent the frames are capable ofexpansion and contraction, as will be obvious. Interposed between theedges of the tongues and the bottoms of the grooves are springs 6, Figs.2, 3, and 5, the

normal tendency of which is to press the supplementary stiles outwardagainst the window-casing and thus create sufficient friction to makethe screen-frame cling to said casings and admit of being moved frombottom to top of the window onthe casing, and

vice versa, without the usual tongue and groove or other appliancesattached to either the casings or to the screen-frame, as will beunderstood.

Two forms of springs are shown, one form in Fig. 2, which consist of twospring-wires 8, having one of their ends bent at a right angle, ornearly so, and driven into the stile proper of the frame, and theirother ends projecting in opposite directions, forming halfelliptics, asshown, and another in Figs. 3 and 5. In the latter case ordinary helicalsprings are shown seated in sockets in the stiles proper, and guide-pinse are used in connection with the springs, as will be apparent uponreference to said Figs. 3 and 5. The guide-pins, however, may bedispensed with, if so desired.

WVhen the frames are not in use, the supplementary stiles are held inposition by suitable hooks f, Figs. 1, 2, and 3, or other appropriatefastenings, as shown in Fig. 8. In this figure I have shown the hooks fsecured firmly in the jamb and spring-plates f secured to thescreen-frame. The normal tendency of the spring-plates is outward, so

that when the jamb and the frame are brought together the hookautomatically engages an opening in the plate. WVhen it is desired todisengage the hook and the plate, it is necessary only to press upon theplate, as will be readily understood. At the top and bottom ends of theframeare arranged guide-plates g and h, the former, which is shown inFig. 7, being secured to the main body of the frame, and the latter(shown in Fig. 6) to the supplementary stiles, as shown in Figs. '2 and3.

It will be seen that the edges 1 andj of the sides and one end of theplate h are turned upward, forming a box, and that a section is removedfrom the center, as will be'understood upon reference to Fig. 6. Theslot or groove formed by the removal of said central section fits aroundthe tongue 0 and aids in holding the plate in position upon the stile,

as will be understood. The edges of the plates g are also turned to formlips or lugs k, which Work between the edges 2' and abut against theparts j and serve to limit the outward movement of the stile D, as willbe understood upon reference to Figs. 3, 4, 6, and 7. The plates 9 alsoserve, as will be seen, to cover the open spaces 3, Fig. 5, and preventthe ingress of mosquitoes at those points.

It will be observed, Figs. 1, 2, and 3, that the Wire cloth or screen islet in flush with the outer surface of the frame, thereby preventingingress of mosquitoes Without reference to the distance to which thesash may be raised, as will be understood. Provision is also made, bymeans of a spring-bolt 0 and a lever for operating the same secured toone of said supplemental stiles, (see Fig. 1,) for fastening the frameupon the inside, so that it cannot be raised from the outside.

Friction-blocks Z, Fig. 2, of rubber, glass, or other suitable material,may be inserted in the edges of the stiles, if desired.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

In a window-screen, the combination of the screen havingthe side piecesor stiles formed each with a tongue, the supplemental stiles providedwith grooves to receive the tongues of the stiles, springs interposedbetween the stiles, plates secured to the screen at the upper and lowerends thereof, and provided at their outer ends with depending lips,plates secured to the supplemental stiles at their upper and lower ends,having slots to receive the tongues of the screen-stiles, and havingtheir side edges turned up to form guides for the lips on the plates ofthe screen, and at their ends formed with lips to engage the lips of theplates of the screen for limiting the movement of the plates on thestiles.

In testimony that I claim the foregoing I have hereunto set my hand this8th day of June, 1889.
